Assembly for a Traction Battery With a Protective Unit, Traction Battery and Motor Vehicle

Abstract

An assembly for a traction battery of a motor vehicle includes a battery module having a cell composite formed by a plurality of battery cells, wherein degassing regions of the battery cells are located on an upper side of the cell composite for letting out a hot gas from a cell housing of the battery cells; a battery component arranged in a vertical direction above the battery module, such that the upper side of the cell composite is facing an underside of the battery component; and a protective unit having a sheet-metal-type protective region for protecting the battery component from the hot gas and a frame-type support region connected to the protective region. The battery component is secured to the support region and the protective region is arranged between the underside of the battery component and the upper side of the cell composite.

         11 . An assembly for a traction battery of a motor vehicle, the assembly comprising:
 at least one battery module having a cell composite formed of a plurality of battery cells, wherein degassing regions of the battery cells are located on an upper side of the cell composite, for release of a hot gas from a cell housing of the battery cells;   at least one battery component arranged in a vertical direction above the at least one battery module, such that the upper side of the cell composite faces an underside of the at least one battery component; and   a protective unit comprising:
 a sheet metal-type protective region for protecting the at least one battery component from the hot gas of the at least one battery module, and 
 a frame-type support region which is connected to the protective region, wherein: 
   the at least one battery component is secured to the support region, and   the protective region is arranged between the underside of the at least one battery component and the upper side of the cell composite of the at least one battery module.   
     
     
         12 . The assembly according to  claim 11 , wherein:
 the protective region, on a side facing the upper surface of the cell composite, comprises a groove-type guide structure which is configured to capture and divert the hot gas.   
     
     
         13 . The assembly according to  claim 11 , wherein:
 the protective region comprises a reinforcement structure in order to increase a rigidity of the protective unit.   
     
     
         14 . The assembly according to  claim 11 , wherein:
 at least some areas of the protective region comprise a heat-resistant and/or electrically insulating material.   
     
     
         15 . The assembly according to  claim 11 , wherein:
 the at least one battery component is a control device of the traction battery and/or a further battery module.   
     
     
         16 . The assembly according to  claim 11 , wherein:
 the protective region, in order to reduce a transfer of heat between the first battery module and the at least one battery component, is arranged with a first spacing from the upper side of the cell composite to form a first air gap, and/or is arranged with a second spacing from the underside of the at least one battery component to form a second air gap.   
     
     
         17 . The assembly according to  claim 16 , wherein:
 the at least one battery component is secured to the support region in a suspended arrangement to form the second air gap.   
     
     
         18 . The assembly according to  claim 17 , wherein:
 the at least one battery component is configured in a form of at least one further battery module having a cell module frame for retention of a cell composite of the further battery module,   the support region at least extends along tie-rods of the cell module frame, and   retaining elements are arranged on the tie-rods, by way of which the at least one further battery module is secured to the support region.   
     
     
         19 . A traction battery for a motor vehicle, the traction battery comprising:
 the assembly according to  claim 11 , and   a battery housing in which the assembly is arranged.   
     
     
         20 . A motor vehicle comprising the traction battery according to  claim 19 .
